Class RowGroupExpandCollapseLayer

    • Constructor Detail

      • RowGroupExpandCollapseLayer

        public RowGroupExpandCollapseLayer​(IUniqueIndexLayer underlyingLayer)

    • Method Detail

      • doCommand

        public boolean doCommand​(ILayerCommand command)
        Description copied from interface: ILayer
        Opportunity to respond to a command as it flows down the stack. If the layer is not interested in the command it should allow the command to keep traveling down the stack.

        Note: Before the layer can process a command it must convert the command to its local coordinates using ILayerCommand.convertToTargetLayer(ILayer)

        Specified by:
        doCommand in interface ILayer
        Overrides:
        doCommand in class AbstractLayerTransform
        Parameters:
        command - The command to execute.
        Returns:
        true if the command has been handled and was therefore consumed, false otherwise.

      • isRowIndexHidden

        public boolean isRowIndexHidden​(int rowIndex)
        Description copied from class: AbstractRowHideShowLayer
        Will check if the row at the specified index is hidden or not. Checks this layer and also the sublayers for the visibility.
        Specified by:
        isRowIndexHidden in class AbstractRowHideShowLayer
        Parameters:
        rowIndex - The row index of the row whose visibility state should be checked.
        Returns:
        true if the row at the specified index is hidden, false if it is visible.

      • getHiddenRowIndexes

        public Collection<Integer> getHiddenRowIndexes()
        Description copied from class: AbstractRowHideShowLayer
        Will collect and return all indexes of the rows that are hidden in this layer.

        Note: It is not intended that it also collects the row indexes of underlying layers. This would cause issues on calculating positions, as every layer is responsible for those calculations itself.

        Since 2.0 it is recommended to use AbstractRowHideShowLayer.getHiddenRowIndexesArray() to avoid unnecessary autoboxing operations.

        Specified by:
        getHiddenRowIndexes in class AbstractRowHideShowLayer
        Returns:
        Collection of all row indexes that are hidden in this layer.

      • getHiddenRowIndexesArray

        public int[] getHiddenRowIndexesArray()
        Description copied from class: AbstractRowHideShowLayer
        Will collect and return all indexes of the rows that are hidden in this layer.

        Note: It is not intended that it also collects the row indexes of underlying layers. This would cause issues on calculating positions, as every layer is responsible for those calculations itself.

        Specified by:
        getHiddenRowIndexesArray in class AbstractRowHideShowLayer
        Returns:
        All row indexes that are hidden in this layer.
